To all whom it may concern:

Be it known that I, VVABD B. STORY, a

citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Automatic Stopping Devices, of which the following is a specification. This invention relates to automatic stopping devices and is particularly designed to be used in connection with newspaper assembling machines although it may be used for any other purpose for which it is adapted.

In the art of assembling newspapers, and in other allied arts, in which it is necessary to feed individual objects, which may be sheets, or folded paper sections, in succession into a machine for any purpose, it is usually important to insure that no more than the required number of sheets, or folded sections, simultaneously passes through the operating mechanism. An object of this invention is to detect the feeding out of an abnormal number of objects from a feeding mechanism. v

A further object of the invention is to automaticallv stop the operation of the machine when the feeding mechanism therefor delivers more than a normal number of objects.

Having these general objects in view, the.

invention consists principally in the provision of means for indicating when any one of a plurality of feeding devices, which are arranged to feed objects into a common passageway, operates to deliver more than a predetermined number of objects into the passageway in any one feeding operation. Other features of the invention will be referred to as the descriptionproceeds.

In the accompanying drawings in which the invention is disclosed in a concrete and preferred form, like reference characters a re used todesignate like parts throughout the several views.

Figure 1 is a diagrammatic view showing a preferred embodiment of the invention.

Fig. 2-is a View: partly in Section and partly in elevation ofpart of a paper feeding mechanism and shows the relation of the stop device operating mechanismthereto.

Fig. 3 is anenlarged detail view looking in the direction of the arrowalong Fig. 2.

rigrras anenlarged" detail vie er the specific stop device operating mechanism shown at the left-hand end of Fig. 1. In the preferred embodiment of the invention, the device is shown in connection with an assembling machine such as is disclosed in the companion application Serial No. 131,674, filed Nov. 16, 1916. In the as sembling machine feeding devices 1, 2, 3, 4, or any other desired number, are employed which are arranged to individually feed the nnrn folded paper sections into a passageway 6 7 leading from opposite directions. to an intermediate delivery passage 39and thence to suitable opening and assembling mechanism, not herein shown. In the operation of such a machine it is essential that onlyone paper section at a time be fed from the feeding devices into the passageway 6.

In order to insure that not more than one. section at a time travels through the passageway means are provided which coop-' crate with each feeding device that will operate when two or more sections are simultaneously fed out to automatically stop the operation of the machine. This automatic stopping means comprises generally the elongated rock shaft 7 which is mounted in a'parallel relation to the passageway 6 on suitable brackets 37 and which is provided at one end with a downwardly extending arm 8 which is arranged to engage and operate a circuit breaker 9. when the arm 7 is rocked. The operation of the circuit breaker has the effect of cutting off the supply of power to the motor which drives the machine.

The means for rocking the rock shaft 7 in order to thus automatically stop the operation of the machine, preferably takes two forms. One form of this operating meansis shown in connection with the feeding devices 1, 2 and 4: and preferably comprisesa nip roll 10 which is arranged in conjunction with the passageway 6 to operate stopping mechanism when it has been deflected to apredetermined extent bythe passage sections thereby. In the case of the feeding device 1 the correspondingnip roll is adjusted tooperate if more than one paper sec tion passes thereby, while in the case of the feeding device 2, the corresponding niproll may be adjusted to permit a paper section from the feeding device 1 and also the feed-Q ing device .2 p to pass; by insuperposed 'rela-;; tion. The nip rolls 10 are carried by the 55 7 arranged to operate the automatic stopping springpressedarms 11 and each-is provided" with an arm 12 which in turn is arranged to engage and turn abell crank 13 about its axis 14 to thereby rock the rock shaft 7 through the engagement of the other end of the bell crank with an arm 15 extending down-.

wardly from the rock shaft 7, It will be seen that by. this arrangement an abnormal depression of a nip roll 10 occasioned by the passage between the nip roll 10 and the feeding-out cylinder 16 of'the corresponding feeding device of more than the normal number of paper sections can be arranged to operate the rock shaft 7 and consequently the circuit breaker in the manner already described.

The construction whereby the nip rolls 10 are resiliently mounted includes the roll supporting arms 11 which are pivotally mounted in the brackets 17 in turn mounted on the supporting rods 18 which extend from 'side to side of the machine and are the feeding devices themselves.

supported in any suitable manner at the ends 111th?)$1d811f16111b613 of the machine framework and preferably so as to beand the arms 12 can be. glven any suitable length to cause them to extend to the rock shaft operating bell cranks 13 to accord with any convenient location in which they may be mounted,

Not only are the nip rolls 10" which cooperate with the feeding-out cylinders 16 of the feeding devices resiliently mounted in the manner shown, but intermediate nip rolls 24 are provided which cooperate with feed rolls 25 mounted intermediately of The feed rolls 25 are preferably driven through the gears 26 which are in-turu directly driven from gears mounted on the shafts of the feeding-out cylinders 16 of the feeding devices.

These intermediate feed rolls25 serve to carry the paper sections along thepassageway -6 when they have passed beyond the influence of the feeding-out rolls themselves. Preferably the nip rolls 24 are not mechanism-since the provision of means cooperating with'each feeding device would be ordinarily sufficient for the purpose, althoughit is obvious that such additional means could be provided where it is found to .be desirable) The bell crank members 13 which are controlled-by the feeding-out devices 1 and 2 and fig, anda feeding-out device correspond:

The arms 12 ing to 1, not shown, arepreferably mounted on a common portion of the framework of the machine as at 27. It willbeqseenlthat the two bell cranks atieither end of the ma chine differ somewhat in their formation because of the respective distances separating them from the corresponding nip rolls 10 from which they are operated. This 'difference in formation shows itself in the arm of the bell crank which is engaged by the operating arm 12. In the one case this arm of the bell crank projects laterally directly from its pivot point. whereas in the. other case it curves outwardly in a direction parallel to the axis inorder to be brought to a position where it can be engaged by the end of the operating arm l2.

Preferably the feeding device 3 which is 1 the most centrally located one of theg'roup,

is provided with a stop mechanism operat-- ing device of a different form than the ones v descrlbe'd. modlfied form of operating device in this One reason for providing a location is because of the lack of space in which to mount an operating device 'ofithe type already described. In this instance the;

operating device comprises a rod 28 which, extends across :t-he'machine just underneath the passageway G and in such relation to the passageway that'the guiding strips 29 thereof rest on itsupper surface. Theguiding strips 29 are supported at, 30 on one fof the supporting rods 18 already described and the free ends of the guiding strips 29, are unsupported except for them engage-z mentwith the rod 28. 'The rod 28is supported at its end directly on the springs 30 which are in turn supported on the bolts 31 threaded into the under side of theside frame pieces. Suitable nuts 32 at the lower ends of the bolts 31 provide a meansifor adjustingthe tension of the spring 30 as needed. The rod 28 preferably passes through a slot 33 provided with a yoke 34 I which is connected at its upper end with short arm 35 projecting laterally fromthe.

rock shaft 7. I This connection takes the form of a bolt 36 which is threaded into the upper end of the yoke 34: and passes through the arm The upper end of the bolt is provided with a spring 37 which bears against nuts 38 provided at theupper end of the boltand tends to hold the" yoke 34in its uppermost position.v It will beseen that by this constructionmeans have been pro:

c I vided which, when more than a, predeterin mined number of paper sections passes through thepassageway 6 at a point adja? cent the bolt 28, the guide strips 29 will be 7 depressed thus bearing down on the bolt28 and movingit downwardly against the pres-' movement of therO Cl 28; as will be apparent,

'sure of the springs 30. This downward.

will'pull downwardly on the"yoke 34 and h s .tu'rn Qt-he' istop. mechanisniw pegating;

shaft 7 about its axis to thereby break the motor circuit.

The arm 8, which directly operates the circuit breaker 9, is preferably loosely mounted on the rock shaft and is preferably moved into operative position by means of the pull spring 40 which is attached at one end to a lug 41 extending from the arm 8 and at the other endto an upward extension on the arm 15. A laterally extending lug 42 from the arm 15 engages a web-13 on the arm 8 and it will be seen that the spring 40 so acts as to hold the lug 42 and flange 43 in engagement with each other. It will be seen that in a movement of one of the bell cranks 13, as shown in Fig. 3, to a. position which will. cause the set screws 44 to engage and turn the arm 15 and rock shaft 7 in a counter clockwise direction, the spring 40 will pull the arm 8 against the circuit breaker 9 and cut off the supply of power to the motor and stop the operation of the machine.

A driving means for the feeding mechanism includes the motor as shown which drives the gear train 45, 46, 47, 48 and 49. The gear 49 drives the feeding-out cylinders of the feeding devices 2 and 3, and a gear 50 drives the feeding device 1 from the feeding device 2. The gears 51 and 52 convey motion from the feeding device 3 to the feeding device 4 which obviously must operate in reverse to the feeding devices 1, 2 and 3. A gear 53 preferably drives a feeding device, not shown, correspondingin a general way to the feeding device 1, at the opposite end of the machine. Feeding rollers 54 and 55 serve to feed paper sections through the curved passages 56 and 57 leading to the deliveryoutlet 39. The gears 5859 and 60-61, operate to drive the feeding rollers 54- and 55 from the feeding devices 3 and 4.
